Description of the new type: [Technical field to which the new type belongs] This creation relates to a load device installed on fitness or rehabilitation equipment to control exercise resistance, especially a magnetically controlled load device, a micro-generator and a The adjustment drive mechanism is completely integrated into a single system, which can be disassembled and used separately, and the change of the magnetic flux density of the load device can be adjusted by electric or manual means to continuously adjust the load resistance in steps. [Prior art] According to US Patent No. 5,711,404, a load setting "MAGNETIC ADJUSTABLE LOADING DEVICE WITH EDDY CURRENT" is a method of using the eddy current resistance formed by the change of magnetic field as a brake (load) method; It is a non-contact magnetic control form, and it is easy to connect with a microcomputer, so the market acceptance is quite high. The basic principle is that by using a conductor placed in a variable magnetic flux, a back electromotive force is generated on a partially closed circuit in the conductor, and a so-called eddy current is generated. The magnetic effect established by the direction of this eddy current flow must be the opposite of that The original magnetic flux direction of the current; and Max-well's Eq knows that the magnitude of this magnetic force is proportional to the square of the magnetic flux density, and this magnetic force can be used as a brake (load) for sports equipment. This type of patent also includes U.S. Patent Nos. 5,879,273, 5,437,353, 5,096,024, 5,072,930, 5,236,069, 5,586,624, and 4,775,145. However, although the eddy current magnetic load device has its advantages and characteristics, if its load part uses a permanent magnet as the magnetic field source, it is difficult to combine it with external digital signals to achieve computerization and dataization. Unless equipped with a separate motor and motor controller, M266073 can change the relative position of the magnet and the conductor, or use electromagnetic coils and an external power supply to overcome this difficulty, but in many cases this external power supply method is inconvenient in use. Therefore, its practicality is greatly reduced; therefore, it is generally used in lower-priced fitness equipment, but at present, fitness equipment pays more and more attention to accuracy and effectiveness, which can only be achieved by computer data; in addition, it has data functions The fitness equipment needs to be equipped with instruments and controllers, and these components require power, so they still need to be supplied from outside, which will increase a lot of problems and limitations. In addition, U.S. Patent No. 6,084,325 discloses a kind of "BRAKE DEVICE WITH A COMBINATION OF POWER-GENERATING AND EDDY CURRENT MAGNETIC RESISTANCE", which uses an external rotating flywheel to generate electricity and supplies a B rake Core power source on the outside of the flywheel. The brake core provides a predetermined eddy current reluctance to the flywheel. This type of load device has sufficient power generation. In addition to supplying the brake core power, it can also provide the required currents such as fitness equipment control instruments. However, the architecture design of the brake core outside the flywheel is designed to meet the needs of large fitness equipment. Set on small fitness equipment, it looks too big or heavy in terms of body shape and weight, it is not easy to use in space, and of course its cost is high, so not all are suitable for all kinds of fitness or rehabilitation equipment. For this reason, the author is actively researching and improving the above-mentioned problem points, and hopes to provide a simple structure, lightweight, and can generate a small amount of electricity as the power to automatically control the eddy current reluctance. [New content] The main purpose of this creation is to provide an eddy current magnetically controlled load device and make full use of the space. Without increasing the volume of the flywheel and internal components, a rotor and stator are skillfully placed in the center of the magnetically controlled load device. The permanent magnets that make up the rotor are set on the inner ring of the flywheel, so that when the flywheel is running, it will become a type of micro-motor M266073. Use the power generated by itself to supply the power required by a small motor. The small motor controls the change in the magnetic flux density between the flywheel and the device to continuously and continuously adjust the load resistance. Another purpose of this creation is that the magnetic control load device is lightweight and convenient for space design. It is used on small fitness equipment and has low cost. Another purpose of this creation is to control the magnetic flux density of the magnetically controlled load device, which can be electrically controlled by a small motor, or manually controlled by a guide wire, which has the functions of electric and manual disassembly and use. . [Embodiment] First, please refer to the perspective view of the embodiment of the first figure. This creation mainly includes: a flywheel (10), a fixed shaft (20), a transmission wheel (30), a driving wheel The belt (33), a micro power generating device (40) set in the center of the flywheel (10), and a magnetically controlled load device (50) set in the accommodation space of the flywheel (10). . Month, 'Only refer to the exploded view of the first figure and cooperate with the cross-sectional view of the fifth figure to show the first and second bearings (12), (13) in the center sleeve (11) of the flywheel (10) (Fifth figure), the inside of the wheel surface (14) is an opening, so that an accommodation space (i5) is formed inside, and a metal conductor (16) is provided on the inner periphery of the wheel surface. As shown in the fifth figure, a transmission wheel (30) is located on the outside of the flywheel (10) for driving the flywheel (10). It can be set to interlock with the flywheel (10), but a better An embodiment is provided with a third bearing (31) between the outside of the shaft hole and the fixed shaft (20), and the inside of the shaft hole drives the flywheel (10) in a positive direction by a one-way bearing (32). The transmission here The wheel (30) can be a pulley or other type of transmission. The diagram is a pulley and is connected to a belt (33). When the belt (33) is connected to a fitness equipment (not shown), the pulley (30) is driven The fixed shaft (20) is rotated, and the one-way bearing (32) is used to drive the flywheel (10) forward. Because the flywheel (10) has inertial force of -7-M266073, when the fitness equipment does not drive the pulley (30), the flywheel (10) can still rotate on the one-way bearing (32) and the first bearing (12) to protect users on some types of fitness equipment from being affected by the flywheel (10). Reverse transmission of inertial force may cause injury. Please refer to the second and fifth figures. The micro-power generating device (40) includes a permanent magnet (41) provided inside the sleeve (11), and a stator core (42) provided on the fixed shaft (20). ), A preferred embodiment, is to fix a permanent magnet (411) on an inner peripheral edge of a ring body (411) protruding from a sleeve (11), and the stator core (42) is provided on a base A coil (421) is wound around (422), and the base (422) is locked inside an accommodation slot (511) in the center of the magnetically controlled load device (50).

This is the principle of a permanent magnet AC generator. This creation uses this principle to use the flywheel (10) as a power source for AC power generation, so that the voltage generated by the stator core (42) passes through an external wire (43) to an AC / DC converter (60), that is, It can supply the power required for the magnetically controlled load device (50) of this creation to achieve electric load control. As for the structure of the magnetically controlled load device (50), please refer to the third to sixth figures, which includes There is: an outer cover (51) whose center is protruded inwardly with respect to the aforementioned micro power generating device (40) at the periphery of the shaft hole to form an accommodation slot (511) for installation; a set of adjusting stators (52) is composed of A pair of arc-shaped magnetically permeable plates (521) arranged opposite to each other is formed by a permanent magnet (522) on the outer edge, a compression spring (523) is provided on the inside, and the two magnetically permeable plates (521 ) —The end is a pivot shaft (524) positioned on the outer cover (51), and the other end is movable Free end (525), and the pivot axis (524) of the two magnetically permeable plates (521) are arranged diagonally opposite to each other and a cable (526) is provided on the free end (525); -8- M266073 an adjustment The plate (53) is provided at its center with a rotary hole (531) that can be sleeved on the outer periphery of the accommodation groove (511), and its upper and lower ends are opposite to the free ends (525) of the two magnetically permeable plates (521). The provided cable (526) is provided with a positioning groove (532) for connection, and a side of the plate body is provided with a circular tooth row (534); an inner cover (54) is matched with the outer cover (51 ), The center is provided with a positioning hole (541) that can be set in the receiving slot (511), and is combined with the outer cover (51) by a number of screws (542), so that the adjusting stator (52 ) And the adjustment plate (53) are positioned between the two cover bodies, and the inner cover (54) is provided with a through hole (543) relative to the arc-shaped tooth row (534); and an electric adjustment drive mechanism ( 55), comprising a small motor (551), a reduction gear box (552), and a driving gear (553) protruding from the bottom surface of the reduction gear box (552), and locked on the surface of the inner cover (54) by screws (554). And the drive gear ( 553) Pass through the through hole (543) of the inner cover (54) and then buzz with the arc-shaped tooth row (534) of the adjustment plate (53). In addition, this creation can also choose to use a manual adjustment method, that is, a surface of the adjustment plate (53) of the magnetic load device (50) further includes a convex card slot (535) protruding from the inner cover (54). An arc groove (544) is provided at the position, and a guide cable (56) for controlling the rotation of the adjustment plate (53) is connected to the convex card groove (535), thereby forming a manual adjustment driving mechanism. Therefore, the author can freely choose to use the electric adjustment drive mechanism (55), or choose to implement the manual adjustment drive mechanism.

M266073 Refer to the fifth and sixth figures for the achievements. This creation is based on the opening. When the flywheel (ίο) rotates, the micro-power generating device (40) can generate power for the small motor (551) to use and borrow The driving gear (553) at the output end drives the adjustment plate (53) for angular deflection. As shown in the seventh figure, when the adjustment plate (53) is deflected clockwise, the upper and lower cables (526) are driven. The free ends (525) of the two arc-shaped magnetically permeable plates (521) are respectively displaced around the pivot axis (524), thereby changing the metal conductors (1) of the inner edges of the permanent magnet (522) and the flywheel (10). … The air gap (D) causes the magnetic flux density to change, which can achieve the purpose of automatically and continuously adjusting the resistance of the motion load. The main feature of this creation is the use of the micro-power generation device (40) clever 5 and 50 times The center of the magnetically controlled load device (50) does not increase the original volume at all, and after experimental test results, the power generated by the micro-power generation device (40) is sufficient for the small motor (551) to use, even as the first As shown in the five pictures, an instrument or controller can still be provided (70) It can be used without any external power supply to achieve self-sufficiency. Another feature of this creation is that the adjustment plate (53) can also be connected with a guide wire (56). When the electric adjustment drive mechanism (55) is not used to control the load , You can directly control the guide wire (56) to change the deflection of the adjustment plate (53) to achieve the effect of dual use of one machine.
